This circuit is a 8-bit binary
<a href="http://en.wikipedia.org/wiki/Counter#Asynchronous_.28ripple.29_counters">ripple counter</a>.
All the <a href="http://en.wikipedia.org/wiki/Flip-flop_(electronics)#JK_flip-flop"
>JK flip-flops</a> are configured to toggle their state on a downward transition of their
clock input, and the output of each flip-flop is fed into the next flip-flop's clock.  So,
when each bit changes from 1 to 0, it "carries the one" to the next higher bit.
